Windows 10: BRAND NEW PC RANDOMLY REBOOTING

I just built my first ever PC AMD Ryzen 5 3600 ASrock b450 steel legend Gigabyte gefore gtx 1660 super gaming OC G.Skill Ripjaws V 16GB 2x8 DDR4-3600 CL16 Crucial P1 1TB M.2-2280 SSD Corsair CXM 650W I DO NOT HAVE THE LATEST BIOS Build seemingly went fine for my first, installed windows 10 pro non-licensed, connected ethernet, installed all windows updates restarting in-between when necessary, then proceeded to install my drivers Primary potential error: Stupidly installed all listed drivers below except those listed as beta and norton from ASrock's website Note I did install my GPU driver correctly from nvidia for the correct model https://www.asrock.com/mb/amd/b450%20steel%20legend/index.asp#Download Afterwards, I installed some standard monitoring software Gpu-z, tweaked some windows settings, and began to install steam, origin, blizzard. I began to download Overwatch, when I experienced my first crash. During the installation the PC rebooted 3 times, which I figured was part of the installation. Logged back into windows each time, reloaded blizzard until the installation finished. I then did the same with Apex, and when that started to crash I got a bad feeling. I went into Windows Event Viewer to find the following errors: A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor APIC-ID: 0 The details view of this entry contains further information. and The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Source: Kernel-Power These would report after every crash. I then: I used whatever AMD monitor software came with the drivers I installed to monitor the CPU to confirm it wasn't overheating I completely disassembled the PC, reseating the motherboard, CPU, GPU, PSU, all cables, RAM, m.2 memory Rebooted, tried to load Overwatch to see what would happen, and crashed I decided to restart my PC and load the boot menu. I reinstalled Windows 10 using the same USB as previously, and deleted all partitions. Clean win10 installation, I did all windows updates again. This time I only downloaded the CPU driver from AMD, and GPU driver from nvidia I still crashed shortly after both driver installations and reboot while idle, monitoring the CPU temp which still only sat 40-50 degrees Celsius Here I am now, not sure what to test or look at. The obvious solution is to try update the BIOS, but I'm worried it'll crash mid-install and break the motherboard. BIOS version currently P3.4 Since reinstalling windows the the drivers I've only crashed the once, but I haven't tried to intentionally stress the system with a large install which is what primarily triggered the crashes previously. Are there any other solutions / tests I can run to see if something else is defective such as the PSU or CPU? Also, could there still be traces or lasting damage for any of the hardware from the incorrect drivers installed? Side note: My biggest error when building the PC was accidentally using the wrong screws that came with my case itself to screw the PSU to the case, turned the pc on once briefly to load the bios, then realized the error and used the right screws. However they were small screws and seemingly connected to nothing within the PSU so I don't think that would've been enough to fry it. Tl;DR Installed the wrong drivers, and I have mysterious system reboots which may be a result of a non-updated motherboard bios..?

PC Randomly Reboots

Just recently, my PC started to randomly reboot, to start it was once every other day, and know every few minutes.
Any suggestions to rectify this problem would be greatly appreciated.

 

808 reboots itself randomly

My brand new 808 reboots itself so often its is unusable. I cannot even access setting or apps-for a short time (half hour) I could, it seemed, but now it reboots randomly while justing sititng there, and sometimes reboots after rebooting.

 

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?
